The conditions are as follows:
1. BME688 uses parallel mode
2. Set 10 points, which are consistent with example (parallel_mode.c):
/* Heater temperature in degree Celsius */
uint16_t temp_prof[10] = { 320, 100, 100, 100, 200, 200, 200, 320, 320, 320 };
/* Multiplier to the shared heater duration */
uint16_t mul_prof[10] = { 5, 2, 10, 30, 5, 5, 5, 5, 5, 5 };
3. Continuous sampling multiple times, no sleep
Problems that arise:
Query gas_index, you will find that occasionally there are several temperature points in the process that do not produce valid data.
For example: gas_index 0~9 can query new valid data in most cases. But in a few cases, for example, when gas_index = 3, there is no data, and finally only data with gas_index of 0, 1, 2, 4, 5, 6, 7, 8, and 9 can be obtained.
Is this normal? If it's not normal, how can I use it correctly? Looking forward to your answer, thank you!

Hi Pai,
You need to check the difference between your code and the reference code.
